RAKE.

SPECIFICATION forming part of Letters Patent No. 706,397, dated August5, 1902.

Application filed March 4, 1902. Serial No. 96,588.' (No model.)

T0 all whom, it may concern:

Beit known that l, ANAH S. ELLIOTT, a citizen of the United States,residing at Mechanicsville, in the county of Cedar and State of Iowa,have invented certain new and useful Improvements in Rakes, of which thefollowing is a full, clear, and exact description.

My invention relates to improvements in rakes especially adapted for usein gathering cut stalks which lay in windrows into shocks preparatory toburning or otherwise disposing of the stalks, althoughthe rake may beused for other purposes. Y

One object of the invention is to provide an improved construction ofthe rake-head in which the teeth are clamped against any possibleendwise or lateral displacement, and at the same time the clampingdevices serve to bridge the space between the 'longitudinal bars of therake-head in order to strengthen the latter'.

A further object of the invention is to provide a simple and durableconstruction of the machine inwhich the parts Aare arranged to alloweasy turning of the machine at the end of the field, and provision isalso made for readily discharging the load accumulated by the operationof the rake.

With these ends in View the invention consists in the combination,construction, and arrangement of parts, which will be hereinafterdescribed, and the actual scope of the invention will be defined bytheclaims.

Reference islto be had to the accompanying drawings, forming part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the iigures.

Figure 1 is a plan view of a rake constructed in accordance with myinvention. Fig. 2 is a vertical section on the line 2 2 of Fig. 1looking in the direction of the arrows. 3 is another vertical section onan enlarged scale, the plane of the section being indicated by thedotted line 3 3 of Fig. 1, also looking in the direction of the arrows.enlarged vertical vcross-section through the rake-head, illustrating oneof the clamps for a rake-tooth, said clamp serving as a bridge for thelongitudinal bars of the rake-head.

Fig. 4 is an of said Fig. 4. Fig. Gis a detail perspective view of onemember of a clamp adapted to secure a tooth in the rake-head. Fig. 7 isan elevation Aof a modified construction of the 5 designates the axle ofthemachine, and G represents the carryingwheels, which are properlymounted on suitable spindles at the The draft-tongue 7 is provided atits rear end with the cross-bar 8,Which is nearly equal in length to theaxle, and this cross-bar of the tongue is loosely connected to the axleby means of the interlocking eyes 9, said eyes being fastened to theaxle and to the tongue-bar 8, as clearly shown by Figs. 1, 2, and 3. Adoubletree 10 is connected to the tongue near its rear portion, and theseatspring 11 is also fastened to the rear extremity of the tongue, saidspring serving to carry the drivers seat 12 and being braced in properposition by means of the stay 13.

A supporting-frame for the rake-head is provided on the wheeled axle,said frame extending rearwardly from the axle and adapted to support themeans for adjusting and locking the rake-head. This frame consists ofthe parallel bars 14 14a, the cross-bar 15, and

f the brace-bars 16, all of these parts being firmly secured together byany approved means. The parallel bars 14 are fastened to the axle, andthey are extended a suitable distance beyond the cross-bar 15. Thebracebars 16 are fastened to the axle and to the cross-bar 1 5,and thesebrace-bars are equipped with suitable'bearings 17, which accommodate thetrip-shaft 18. Said trip-shaft is disposed across the carrying-frame inrear of the seat, and said shaft is provided at :its end On the crossbar15 yof the frame are provided suitable 'keepers 20, which receive theslidable latch- `bolts 21, the latter being provided at their front endswith the slotted heads 22, adapted to receive the crank-arms 19 ofthetrip-shaft 18. The trip-shaft is held normally in an active position bymeans of a coiled spring 23, which is attached to a portion of thetripshaft and to the cross-bar 15, and to said tripshaft is operativelyconnected a link 24, the front end of which is attached'to a crank 25 ona treadle-lever 26, the latter being pivotlOO ally mounted, as at 27,von the axle and having a foot-piece 28, which is disposed withinconvenient reach of the drivers foot, all as shown more clearly by Fig.3.

The side bars 14 14a of the supporting-frame are provided at theirextreme rear ends with suitable open bearings 29, which are disposed intransverse aliuement and serve to loosely support the rake-head, so asto permit the latter to turn on its axis. The rake-head is disposed inrear of the axle 5, parallel to the latter, and this rake-head is muchlonger than the axle in order that the end portions of the rake-head mayextend for considerable distances beyond the opposite sides of thecarrying-wheels 6, as shown more clearly by` Fig. 1. The rake-headconsists of longitudinal bars 31, a plurality of double-ended teeth 32,and a plurality of clamps` which are individually engaged with the teethand have interlocking engagement with the parallel bars 30 3l, so as tormly hold the said teeth 32 against endwise or lateral displacementwithin said parallel bars, each clamp serving to bridge the spacebetween the bars and the series of clamps affording spaced bridges tothoroughly brace the bars forming the rakehead.- The parallel bars 3Q 31are designed to extend the full length of the rake-head, and these barsmay be of any appropriate size and material. Each tooth 32 consists of ametallic bar having the substantially rectangular form in cross-sectionshown by Fig. 5, and the end portions of each tooth are beveled ortapered, so as to produce the two points indicated in Figs. 2 and 3.Each tooth 32 is engaged at or about its middle by one of the sectionalclamps, and as said clamps have interlocking engagement with theparallel bars it is evident that the series of teeth will be secured attheir middles.

Each clamp consists of the members 33 34, one form of the clamp beingshown more particularly by Figs. 4, 5, and 6. Each member of the clampis cast in a single piece of metal substantially in the form shown bythe detail view in Fig. 6 of the drawings, and said clamp member isprovided on its inner face with the longitudinal anges 35 36. Theflanges 35 36 of each clamp are disposed parallel, so as to form anintermediate groove or space 37, and said flange 35 is widened at oneend,.as at 35, so as to form an abutment 38, while the companion iange36 of the member is widened at the other end, as at 36a, thereby forminganother abutment or shoulder 39. Each member of the clamp is provided onits outer face with the transverse ribs 40 and with the longitudinal rib41.

IIn applying the two-part clamp to the parallel bars 30 31 of therake-head suitable grooves 42 are cut in the opposing faces of the barsand the members 33 34 of the clamp are adjusted across the inner facesof the bars and in positions for the ribs 41 to enter the grooves 42,while the transverse ribs 40 of said clamp members will embrace the topand bottom edges of the bars, as clearly shown by Fig. 4. The members 3334 are applied in reversed positions to the bars 30 31 in order that theactive inner edges of the iianges on said members will bear against oneanother and the abutments or shoulders 38 39 will have the interlockingengagement represented more clearly by Fig. 4. The bars 30 31 are drawnfirmly upon the members of the clamp by means of the screw-bolts 43, twoof which are passed through said bars on opposite sides of each clamp,as clearly shown by Figs. 4 and 5. These bolts serve to draw the barstoward each other and to press the members of the clamp firmly upon theedge portions of thev double-ended' tooth 32. The members of the clampsare interlocked together and to the bars 30 3l by the engagement of theianges and the ribs, and by interposing the tooth 32 within and betweenthe members of the clamp the parts are prevented from lateral as well asendwise separation. The tooth is so firmly gripped in the clamp that itcannot become displaced in any direction; but in the event of breakageof any tooth the bolts can be loosened and the members of the clampseparated, so as to permit the Withdrawal of a broken tooth and itsreplacement by a new tooth.

The rake-head thus far described is loosely mounted in the bearings 29of the rake-frame, and said rake-head is equipped with two pairs of arms44 45, said arms being braced by the stays 46. In the position of therake shown by Figs. 1, 2, and 3 the forwardly-extending arms 44 areengaged at their front ends with the bent ends 2la of the latch-bolts,whereby the rake-head is held firmly in a position wherein its teeth 32are inclined slightly in an upward and rearward direction.

In the operation of the machine it is drawn across the fields, and thelower portions of the double-ended teeth serve to drag or rake the cut.stalks until a certain quantity of stalks shall have accumulated. Atthis time the operator presses on the lever 26, so as to pull the rod 24in a forward direction and against the energy of the spring 23, therebyturning the trip-shaft 18 and making its crank-arms 19 pull the latches21 forwardly. This operation of the latches disengages the hookshapedends 21a thereof from the arms 44, thus releasing the rake-head andpermitting it to turn or rotate for a half-revolution within thebearings 29, whereupon the rake is reversed, so that the other pair ofarms 45 will engage with the bent ends of the latches 21, and the rakewill then become locked in another active position.

In Fig. '7 of the drawings Ihave illustrated a slightly-modified form ofone tooth-clamp. This clamp consists of the matching members having themechanical features of construction heretofore described; but instead ofWidening the flanges 35 36 for one-half the length thereof I prefer toonly widen the flanges enough to secure the abutments or ICJ shoulders38a 39, as will be clearly understood by reference to said Fig. 7.

The employment of the bar 8 at the rear end of the tongue and the looseconnection of said bar to the axle nearits end portions enables themachine to be turned easily at the end of the row. The seat-spring 1lextends rearwardly from the tongue, so as to overhang the axle, and thisarrangement of the seat serves to dispose a part of the weight of theoperator in such a manner as to somewhat counterbalance the tongue.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. In an apparatus of the class described, a rake-headconsisting of longitudinal bars, a series of teeth, and a correspondingseries of clamps, each clamp consisting of complementary members havinginterlocking connection one with the other and adapted to be securedrmly to the bars of the rake-head.

2. In an apparatus of the class described, a tooth-clamp comprisingcomplemental channeled members provided in their opposing faces withprojecting shoulders, said shoulders of the members being assembledinteinterlocking engagement, whereby the shoulders limit endwisedisplacement of the members relative to each other.

3. In an apparatus of the class described, a rake-head, consisting oflongitudinal bars, a series of clamps interposed between said bars andeach consisting of members which have interlocking engagement with eachother and with the individual bars of said rake-head, and a series ofteeth having individual engagement with the members of the clamps. A
